To all whom it may conccm:

- Beitknown that. we, HIERONYMUS LER aIIdJOHN GROSS, of Decatur, in thecounty of Macon and State of 1 Illinois, have invented a new and usefulImprovement inWater-Regulators, which improvement is fully set forth Theobject of our invention is to so construct a water-regulator that aregular amount of pressure is maintained in the supply-pipes in I thebuilding, irrespective of the pressure in the water-mains; and consistsin the construction of a receiving-chamberand escaping-chamber inside ofthe case;';also, in the construction of the plunger with two (2)cup-shaped and balanced disks, so thatjthe pressure is received equallyon the concavity of the disks from the Y water in the mains, and on theconvexity of the disks from the "supply-pipes of the building, 1 thesebalanced disks causing the regulator to I work smoothly and noiselessly,and without jar .jto the supply-pipes when thewater-cocks are I closedor opened, bycreatin g a friction between saiddisks and the guides forthe same.

A is the casing B, the inlet, and G the outlet; D, thereceiving-chamber, and E the upper or escaping-chamber, the chamber Ehaving the inlets a a and outlets b b. The valvechambers are secured inthe casing with the nut F, having packingat ff. G is the plunger,working in guides g g g in the chambers.

H is a valve betweenthe inlets a a and out- "lets b I). disks, securedto the plunger by the thimble I I are the cup-shaped balanced t and nutj. J is a diaphragm, secured to the plunger by the nut k and to thecasingby the cap K. L is-a spiral spring on the plunger, the amount ofpressure being regulated-with the thumb-screw M, operating on theplunger through the spring. N is an escape-valve,

valve. W I

The regulator operates as follows, viz: Water is admitted into thereceiving-chamber, and passes through the inlets a a into the upperchamber, and from thence through the outlets b b into the casing, andthrough the supplypipes of the building. Loosening the thumbs'crew.causes the spring to raise the plunger, closing the valve H, anddecreasing the supply, while tightening the thumb-screw depresses theplunger, and increases the throw of the plunger and the opening of thevalve H. When water is drawn from the supplypipes the pressure isdecreased in them andin the casing, causing the spring to depress thediaphragm, plunger, and valve H, and allowing the water to pass from thereceivingchamber into the upper chamber and casing until the pressure issufficient to raise the diaphragm, spring, and plunger, and close thevalve.

- The two cup-shaped balanced disks in the chambers being opposite toeach other, and

receiving the pressure of the water equally from the main, prevent thetoo quick working of the plunger, and. avoid the thumping and jarring ofthe pipes, as if a single disk were used. The bottom of the receiving-chamher, as well as the top of the upper chamber, being open, an equalpressure is had from the Water in the casing and supply-pipes on theopposing sides of these two disks. Afriction is created between thedisks and the guides that greatly assists in retarding the motion of theplunger.

When a boiler for heating water is used in the building, and full ofcold water, the water, when heated, expands and causes too great apressure in the supply-pipes. This pressure is relieved by theescape-valve N, which should be set to greater pressure than.that of.the

spring L.

Having thus described our invention, what we claim as new, and desire tosecure by Let- 'ters Patent, is-- pipes of the building, on theconvexity of the disks, substantially as and for the purpose set forth.

2. The receiving-chamber D, upper chamber E, balanced cup-shaped valvesI I, inlets a a, and outlets b b, in combination with the valve H,substantially as shown and described.

3. The combination of the spring L, thumbscrew M, casing A, plunger G,chambers D E,

valve H, and balanced valves I I, substantially as shown and described.
